' T0 710 it may concern: 0 i i Be it known that I, WILHIFILM' Gor'rni'm" SoHRtiDER, manufacturer, a citizen of the free town of Liibeck, in-the Empire of Germany, and resident of :Liibeck, Germany, have invented newand useful Apparatus.

for Homogenizing Milk'iand other Liquids, of which the following is V a specification.

The present invention relates to a new apparatus for homogenizing liquids be tween surfaces pressed against each other.

When milk is pressed between two carethe distance from the' se'at of the valve to the cone of the valve is a Tconstant figure at .ticles which areof a diameter smaller than the distance between valve seatrand valve cone can, of course,

fundamental principle, which has been employed in the new apparatus consistsin obtaining this gap between the homogenizing surfaces as small as possible. This can, on the one hand be obtained, by. employing 7 very large I'surfaces, which, however, 1n

practice would .ofler very greatdisadvantages, 0r,several seats and cones may be arranged, as shown in the accompanying drawing, above each other, through which the liquids to be homogenized is then forced. '35.

It is obvious, that at. a given pressure and at a given diameter the distance between the several seats willbe only a fraction of the distance between the seat and cone of an apparatus with one T-homogenizing surface only. For instance, if .in an apparatus employing only two working sur-' faces,

the distance between these surfaces were 0.01 mm., then at the-same pressure and diameter the distance between the working surfaces in the present invention, employing, for instance, five pairs of conical "members, would be only 0.01-: 5 or 0.002 mnl.

Therefore the. present apparatus must,- under otherwise equal conditions, produce amuch finer product or in other words,

ground surfaces, resembling the cones zofa'valve and pressed against each other,

. beno more disintegrated between the homogenizing surfaces The i V V Specification of Letters Patent. 1 a 'np'plicationflled l lovember 26, 1913. Serial R0.

are disposed the circular members 6 and c this mouthpiece which are carefully ground against each other. The members 6 eachcarry two conical working'surfaces on their inner side. These two working, surfaces 'fit accurately the two conical working surfaces carried by each of the members 0 'on their outer side. The membersb fit intothelarge bore of the mouthpieces with a snug fit. The

top member at is; provided with a stem d,

preferably of a cross-shaped section and serving asa guide'for the several members.
